MINING-MACHINE TRUCK.

SPECIFICATION forming part of Letters PatentV No. 702,817, dated une 17, 1902.

Application filed November 2l, 1900. Serial. No. 37,290. (No model.)

To all whom, it may concern:

Beit known that I, ALEXANDER PALMRos, a citizen of Finland, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Mining-Machine Trucks, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l represents a side elevation of the entire apparatus with a cutting-machine (indicated by dotted lines) in position thereon. Fig. 2 is a plan view of the transporting mechanism detached from the cutting-machine. Fig. 3 illustrates the positions of the two parts 0f the mechanism just as the cutter-machine part is beginning to be drawn up onto'the truck part. Fig. 4 is a section on the line :z: of Fig. 2 on a larger scale. Fig. 5 is a section of the line y y of Fig. 2 on a larger scale. Fig. 6 is a detail view of the clutching devices which unite the two parts of the mechanism on a larger scale. Fig. 7 is a sectional detail of the lower or receiving end of the truck part of the apparatus, illustrating its construction more fully. Fig. 8 isadetached sectional detail of the ratchet mechanism.

The two essential parts of the mechanism to which this invention relates are the cutting apparatus and the transporting apparatus, the purpose of the invention being to so construct these parts and so relate them that they can effectually coaet in transporting the cutting apparatus from place to place, as from one room in the mine to another.

The cutting apparatus herein illustrated is indicated as a whole by A. inasmuch as there can be considerable variationwith respect to this without departing from the essential features of theinvention, itis not necessary to illustrate or describe the two parts of this mechanism in detail. The one illustrated has a bed-frame and a carriage provided with a cutting apparatus and a motor on the carriage. At a special place in the gearing and shafting provision is made for clutching them to power-transmitting parts on the transporting apparatus. Any suitable devices can be employed for this purpose, and the motor, its armature, and the shafting and gearing can be arranged in any preferred Way that will permit them to accomplish their several purposes and also allow them to be connected in the manner here contemplated. As shown in the p resent mechanism, the motor has its armature-shaft arranged longitudinally on the machine, and the gearing and shaftinginterposed between it and the cutting apparatus are placed in front of the motor. The armature-shaft is extended backward beyond the commutator and beyond the rear bearing, the latter being provided with one member of a clutch mechanism, as indicated at E. The other member of the clutch is shown at U. This clutch is for the purpose of connecting the miningmachine or its motor to the mechanism on the transporting-truck, by means of which the machine or motor can be utilized to eect its own propulsion bodily from place to place.

The truck is indicated as a whole by V. It has the bed part fr, mounted on the axles o' U2,which latter are secured to the truck-wheels o3. At one end the bed part V is provided with a transverse shaft V', suitably mounted in bearings t t2 on a transverse binder-frame t3. The bearing t2 carries a worm-gear at V2, with which a Worm-pinion u on the shaft u engages, the shaft u carrying the aforesaid clutch element U', as shown. The shaft V is connected to the axle c by a driving-chain c3, and the two axles are connected together by a supplemental driving-chain o4. ABy this means motion imparted to the'shaft u will be transmitted to the axles 'u' o2. i

WV is a shaft mounted in bearings W5 on the transverse frame t3 at the rear end of the truck-frame and adapted to he rotated by means of a ratchet-and-lever mechanism at w w wl. The shaft W has a sprocket-wheel w', from which a chain W extends to asprocketwheel W2, near the front end of the truck and below the bottom thereof. The pawl w7 of the ratchet mechanism is double-ended, as shown in Fig. 8, and is adapted to act alternately against opposite sides of the ratchet- Wheel ws, so that the ratchet-wheel may be operated in either direction to correspondingly operate the chains W' in either direction. Along the top of the truck there is IOO with one of the bed cross-bars a.

supported a channel or guidewayws, in which the upper part of the chain W runs, and the chain being endless it can be connected by means of lugs 104 to the bed of the cuttingmachine, the lugs being adapted to engage one of the bottom cross-bars a', as shown in Fig. 3. Inasmucli as this chain is capable of having power imparted to it in either direction, as before stated, it is possible not only to drag the cutting apparatus from the ground up onto the truck, but also to drive or push it from the truck over the front end when desired.

The manner of operating the parts above described will be readily understood. When the cutting apparatus is to be placed on the car or truck, the front end of the latter is tipped slightly, as shown in Fig. 3, and the rear end of the cutter is placed thereon in such a position that the lugs 104 will engage Then by the pawl-and-lever mechanism the chains are rotated and the machine is pulled back far enough to have the two parts E U' of the above-described clutch come into engagement. Then the current can be admitted to the motor, and the shaft u will be rotated, with the result that the driving-chains v4 will rotate the axles and the truck-wheels Q23 and the machine thereby carried to any place that may be desired. Vhen it is necessary to again remove the cutter, the endless chain W is rotated in the opposite direction, and its lugs 104 will positively7 move the cuttingmachine off and over the front end. In this respect the mechanism is greatly superior to those heretofore used, in which parts were employed that require the pushing of the machine oif from the truck by crow-bars or other manually-operated tools. I also believe myself to be the -first to have provided a transporting device of this class having a fixed power mechanism at the rear end,with a clutch element so arranged that it is brought immediately into action and caused to engage with its counterpart at the instant that the cutting apparatus reaches the rear end of its movement. f

What I claim isl. In a combined coal cutting and transporting mechanism, the combination of the truck, the supporting-wheels,the power-shafting, means connecting the power-shafting to the supporting-wheels, the worm-gearing, the clutch element, and the separable cutting apparatus, having an electric motor and counterpart clutch element, said cutting apparatus being adapted to be drawn to such position on the transporting mechanism as to have the two clutch elements mutually engage,sub stantially as set forth.

2. In a combined coal cutting and transporting mechanism, the combination of the truck, the supporting-wheels, the transverse y shaft, the sprocketgearing connecting the transverse shaft with the supporting-wheels, the longitudinally-arranged shaft, the wormgearing connecting the longitudinal and the transverse shafts, the clutch element on the longitudinal shaft, and the cutting apparatus adapted to be drawn onto the truck, and having a clutch element counterpart to, and adapted to be engaged with the aforesaid clutch element, substantially as set forth.

3. In a transporting-truck for transporting mining machines, the combination of the platform having a guideway for the miningmachine, the supporting-wheels, the endless chain mounted longitudinally of the platform and adapted to move a mining-machine such as aforesaid positively off from the platform, or positively onto the platform, and reversible power devices for actuating said chain, substantially as set forth.

4. In a wheeled truck for transporting mining-machines, the combination of the platform,the supporting-wheels,the endless chain mounted longitudinally of the platform and adapted to detachably engage with the mining-machine and move it longitudinally, and means for imparting power to the chain substantially as set forth.

5. In an apparatus comprising a wheeled truck and a separable mechanism adapted to be transported by the truck and provided with a motor and a rotary power-transmitting element actuated by the motor and otherwise having a fixed position, the combination of the truck frame, the wheels thereon, the power-transmitting devices connected with the wheels,the initial power-receiving elem ent actuating said power-transmitting devices having a xed position and adapted to mesh or be engaged with the power-transmitting element on the separable mechanism when the latter is moved bodily onto the truck, substantially as set forth.

6. In an apparatus comprising ,a wheeled truck and a separable mechanism adapted to be transported by the truck and provided with a motor, the combination of the truck-frame, the wheels thereon, the power-transmitting devices connected with the wheels, and a shaft longitudinal of the truck, said separable mechanism having also a longitudinal shaft adapted to be actuated by its power devices, and means for connecting said longitudinal shafts.

In testimony whereof I affix my signature in presence of two witnesses.
